There is a long Note in compiler/GHC/Driver/GenerateCgIPEStub.hs which describes the implementation. As far as the interface is concerned, it's quite straightforward: * One can call GHC.Stack.CloneStack.cloneMyStack, which returns a "frozen" copy of the calling context's stack * One can then call GHC.Stack.CloneStack.decode to decode the stack into a list of frames. Did you have any particular questions? Cheers, - Ben
